A touch screen is a type of electronic display panel that can detect and respond to human touch or input. It allows users to interact with a device by touching icons, buttons, or other graphical elements on the screen, rather than using a mouse, keyboard, or other input devices.
Touch screens are commonly used in smartphones, tablets, laptops, ATMs, information kiosks, and other devices. There are several types of touch screens available, including resistive, capacitive, infrared, and surface acoustic wave (SAW) touch screens. Each type of touchscreen technology has its own advantages and limitations in terms of accuracy, sensitivity, durability, and cost.
Touch screens have become increasingly popular due to their intuitive and user-friendly interface, which makes them ideal for a wide range of applications in various industries.
